ABC issues news releases on the latest workforce, policy and industry issues, as well as construction-related economic data and trends. Commercial and industrial construction economic analyses include federal data on construction spending, employment, GDP and the Producer Price Index, as well as state-by-state construction unemployment estimates.

In addition, ABC produces the Construction Backlog Indicator, the only economic indicator that reflects the amount of work that will be performed by commercial and industrial construction contractors in the months ahead, and the Construction Confidence Index, a diffusion index that signals construction contractors’ expectations for sales, profit margins and staffing levels. ABC construction economic releases are published according to this schedule.

WASHINGTON, Jan. 11—Overall construction input prices declined 0.1 percent in December, yet despite the lack of inflation for the month, prices are up 5 percent on a year-over-year basis, according to an Associated Builders and Contractors (ABC) analysis of Bureau of Labor Statistics data released today. Nonresidential construction materials prices also declined 0.1 percent for the month and are up 4.8 percent from the same time one year ago.

Energy prices have been more volatile lately. Natural gas prices increased 13.7 percent from November, but are 6.3 percent lower on a year-over-year basis. Crude petroleum prices rose 16.4 percent between December 2016 and December 2017 and have been climbing higher during the first days of 2018.

“Given stronger global and domestic economic growth, elevated liquidity in international financial markets, burgeoning trade disputes and efforts by certain energy producers to limit supply growth even as prices rise, one would have expected a sharper increase in construction materials prices in December,” said ABC Chief Economist Anirban Basu. “The fact that inflation remains contained should be viewed by most contractors as very good news. Not only are many contractors vulnerable to sudden increases in certain materials prices, but faster inflation can trigger higher interest rates, which ultimately reduce the demand for construction services.

“Though the overall Producer Price Index (PPI) indicates low December inflation, a number of materials prices increased, including iron and steel and the category that includes prepared asphalt,” said Basu. “Softwood lumber prices, by contrast, fell.

“Despite December’s reprieve from rising inflationary pressures, many economists expect inflation to become more apparent as 2018 proceeds,” said Basu. “Recently enacted federal tax cuts stand to supercharge the economy, which should translate into more construction starts later this year and into 2019. At the same time, growth in Europe and in much of Asia remains solid. India’s economy is expected to expand more than 7 percent this year, and China’s by more than 6 percent. The upshot is that December’s data may come to represent an exception during an increasingly inflationary period.”
